The invention relates to the technical field of tail gas treatment, in particular to a tail gas aftertreatment device and a diesel engine tail gas treatment method. The heating device is arranged on the post-treatment mixer; a heating field is formed in the heating device, and exhaust airflow of the post-treatment mixer flows through the heating field; the heating device is connected with the temperature control system, the detection result of the heating device is transmitted to the temperature control system, and the temperature control system can control the heating device to be started and stopped according to the detection result. According to the tail gas after-treatment device, the heating device is arranged at the proper position of the after-treatment mixer so as to form the temperature field, exhaust gas flow is heated before nitrogen oxides in tail gas are removed, the exhaust gas flow can make full contact with the temperature field, and therefore efficient heating operation on the exhaust gas flo
